COMBINED DIE AND MARKER.

Application filed, February a, 1924. Serial No. 691,525.

To all whom it may concern:

:Be it known that I, FRANK ENGEL, a citizen of the United States ofAmerica, and a resident of Little Falls, in the county of Herkimer andin the State of'New York,

iave invented certain new and useful Im provements in Combined DiesandMarkers, of which the following isi specification- This inventionrelatestodies and particularly to devices of this charactcriadapted tocut from sheets of material blanks to housed in the 'manufactureof bootsand shoes.

Obviously blanks of this character must be of different sizes accordingto the sizes of the boots or shoes to be manufactured therefrom and itis necessary that such blanks be marked properly to indicate the size ofthe boot or shoe in the manufacture of which they are designed to beused.

The object of the present invention is to provide eachdie with markingdevice per-.

manently attached thereto which Will mark the size of the blank at thesame time said blank is being cutfrom a sheet of material.

The invention cQ lSists primarily in providing each cutting diewith acrossbar on whichis mounted a marking device so constructed as tooperate during theeutting of ablank by said die. i

The invention further consists in certain novel features of constructionand'arrangement of parts which will be understood'readily by referenceto the description of the drawings and to theclaims, to be. hereinaftergiven.

For the purpose of illustrating the invention, one preferredform thereofis illustated in the drawings, this form having been found to givesatisfactory and reliable results although it is to be understood thatthe various 'instrumentalities of which the invention consists 'ca'nfbevariously arranged and organized and the invention is not limited to theprecise arrangement and organization of these instrumentalities asherein shown and described except as required by the scope'of theappended claims.

Ofthe drawings Figure 1 represents an inverted plan of a cutting dieprovided with a marker and embodying the principles of the presentinvention.

Figured? represents a transverse section on line 2, 2 on'Figi-l showingthe various,

elements of the marking device in their normal position,

Figure 3 represents a transverse section on line 2, 2, on Fig. 1,showing the various elements in position tomark a blank at the same timethat it is being cut, and

Figure 1 representsan elevationof a portion of one side of the dieshowing the means for securing the.crossbar 'on hridge to the die. i i

Similar throughout the several figures'i'of 'the drawings.

In the dawings 10 is a cutting die of a shape toout out a sole to beused in the,

manufacture of boots and shoes or an inner sole to be used in thecompleted shoes, said die having a knife edge 11 at the bottom, and afiat portion 12 at the top thereof againstv'hich the beam of a press isadapted to coact to force the die through the material from which thesoles are to be out.

It is essential that the soles out by the die should be suitably markedto designate.

the of shoe in which they are to be used.

Qhyiously it is of great advantage to cut the. sole andmark it atthesame time, thereby saving'both time and labor and reducing i the cost ofthe finished articles.

The cutting die 10 has dovetailed into its. opposite sides a bridge orcrossbar 13 having an opening 14 therein through which ex tends anL-shaped member 15 pivoted at 16 to a block 17 secured to the under faceof said bridge 13 by means of screws 17*.

The block 17 hasa walled recess in its lower end in which is positioneda member 18.pivoted at 19 to said block and provided with a size number20 or other designating character. y

This member 18 is pivoted at 19 to said block 17 and is. adapted to bemoved about its pivot to bring the marker or size number 20 into contactwith an ink pad 22, the rear end of which is embedded in a recess in theportion 23 of said block 17.

The bridge 13 has an opening 21 therein through which the ink pad 22 maybe. supplied with ink. j

The L-shaped member 15 has a stop pin 2 L extending from the arm 25thereof which is adapted to limit the outward movement of said memberabout its pivot 1 6. by contacting with the under face of the bridge orcrossbar, 13;-

characters indicate like parts The normal position of said L-shapedmember 15 is as shown in Fig. 2 of the draw ings with the corner 26considerably above the upper face of said bridge 13. hen in thisposition the marking member 18 is forced about its pivot 19 by thespring 27 and the size number 20 is thus retained in contact with theink pad 22.

When the cutting die 10 is placed upon a sheet of material upon asuitablebed and the beam of a press is moved downwardly thereon toeffect the cutting of a blank, said beam will first contact with thecorner 26 of the L-shaped member 15 and the continued movement of thebeam will move said L-shaped member downwardly about its pivot 16, thelower inner corner of the arm 25 during this operation bearing againstthe side of the marking member 18 and moving it about its pivot 19 intothe position shown in Fig. 3.

At thistime the upper faces of the bridge 13 and member 15 are alinedand the further downward movement of the press beam will force the knifeedge 11 of the die 10 through the material and at the same time causethe marker 20 to impress the size number upon the blank cut from thematerial.

By having the marker 20 permanently attached to each die 10 no mistakesare possible for the correct size number will always be impressed uponthe blank.

Another advantage of combining the marker with the die is that severalblanks cannot be cut from the die at the same time for only one of theblanks would be marked and a left blank cannot be cut with a right dieas the blank would be marked on the wrong side.

It is obvious therefore that when this device is used better resultswill be obtained inasmuch as each blank must be out separately with theproper side of the blank cut provided with the correct size number.

With this explanation it is believed that the operation and manyadvantages will be apparent.

Having thus described my invention, '1 claim 1. A cutting die having anendless knife edge and provided with a marking means positioned betweentwo opposed portions thereof and operable during the cutting operation.

2. A cutting die having an endless knife edge and a cross bar extendingbetween two opposed portions thereof said bar having mountedthereonmeans for marking the blank cut by said die and operable duringthe cutting operation.

3. The combination of a cutting die; a cross bar thereon; and pivotedmeans on said bar for marking the blank cut by said die.

e. The combination of a cutting die; 21

cross bar thereon; an ink pad on the under face of said bar; and amarker normally contacting with said pad and adapted to be moved intoposition to'mark a blank being cut by said die.

5. The combination of a cutting die; a cross bar thereon; an ink pad onthe under face of said bar; and a pivoted marker normally contactingwith said pad and adapted to be moved into position to mark a blankbeing out by said die.

6. The combination of a cutting die; a cross bar thereon: an ink padsecured to the under face of said bar; a member pivoted to said bar;pivoted means coactingwith said member and having a portion thereofnormally above said bar; and a marker on said member in contact withsaid pad when said pivoted means is in its normal posit-ion.
